Hinge makes a slight crinkly sound

Hi,

Whenever I open the lid of my surface book 2, the hinge makes a slight crinkly sound, like a plastic wrapper being folded. What part of the hinge might be causing this? (Might it just be the flex cable moving?). Might this lead to a more serious issue, or should I just live with it (it is only a very mild sound after all). Is there anything I can do that might help reduce/fix this sound? (Besides from getting it replaced)
